Performance of Some Modified Ordinary Ridge Regression Estimators
Abstract: In multiple linear regressions, if the data suffer from severe multicollinearity, then the ordinary least squares (OLS) method become more sensitive to it, and in such a case OLS could yield wrong sign for some of the regression coefficients. Therefore, when such a situation arises, we could use one of the biased regression methods viz., ridge regression, principal component regression, and so on, as an alternative method to OLS. This …

Comparative Evaluation of Pedigree-Based and Genomic BLUP Models for Wheat Grain Yield Prediction
Abstract: Before genome-wide molecular markers became affordable, plant and animal breeding relied on pedigree-based prediction (P-BLUP), using the expected additive relationship matrix (A) derived from recorded ancestry. Genomic selection replaced or augmented this with a marker-derived genomic relationship matrix (G; GBLUP), and single-step methods combining A and G are now standard when only a subset of a breeding population is genotyped. It is less clear whether pedigree information retains any predictive …

Study of Uncertainty Quantifications for Designing Smart Systems
Abstract: Uncertainty is an innate piece of this present reality. No two actual examinations at any point produce the very same result values and numerous significant sources of info might be obscure or immense. Uncertainty impacts practically all parts of designing displaying and plan. Engineers have long managed estimation mistakes, unsure material properties, and obscure plan request profiles by including elements of wellbeing and widely testing plans. By more profoundly getting …

Incorporating Material Fatigue Parameter Determine in The Rolling & Sliding Contact Fatigue Analysis of Gears
Abstract: As the material's intricate stresses and strains are always shifting during phases of loading, determining the predicted equipment working under rolling-sliding contact loads and their fatigue lives (wheels, bearings, and gears) is particularly difficult. Another difficulty is not knowing the precise characteristics of the material used to make the components, which is particularly noticeable. when it comes to heat-treated components, where the material characteristics' values can differ greatly among the …
